Embodiment

[0016] The invention provides a method for making a dual-activation photocatalyst. The composition of the dual-activation photocatalyst is: 4.8-8.6% doped nano-titanium dioxide, 0.9-1.6% rheological agent, 1.2-3.8% nano-silver ion, 1.6- 1.9% dispersant, 0.8-1.2% defoamer, 22-34% hydrosol, 1.2-1.8% anti-fogging agent, 44-70% purified water and 3.1-3.9% calcium metasilicate.

[0017] Preparatory work is carried out first, and various raw materials are prepared, and then various equipment for processing are prepared, including high-temperature reactors, heating devices, temperature sensors, stirring devices, dryers, cooling water tanks, mills and screens; Put all the raw materials into the high-temperature reaction kettle in turn, turn on the heating device to heat, and stir evenly through the stirring device until the liquid double-activated photocatalyst is stirred into a paste; then put the paste-like double-activated photocatalyst into the dryer for drying , and then take it ...

Abstract

The invention discloses a preparation method of a double-activated photocatalyst. The double-activated photocatalyst comprises 4.8-8.6% of doped nano titanium dioxide, 0.9-1.6% of rheological agent, 1.2-3.8% of nano silver ions, 1.6-1.9% of dispersing agent, 0.8-1.2% of defoaming agent, 22-34% of hydrosol, 1.2-1.8% of anti-fogging agent, 44-70% of purified water and 3.1-3.9% of calcium metasilicate. The product has the advantages of being small in particle size, high in oxidation capacity, uniform in film forming and good in adhesive force; inherent characteristics of a high-order product canbe well excited under the low-light condition, so that formaldehyde, benzene series, TVOC and other pollutants can be rapidly, efficiently and lastingly decomposed; meanwhile, the functions of long-acting bacteriostasis, disinfection and deodorization are achieved; besides, the double-activated photocatalyst has a good pollutant removal effect and is proper in cost and suitable for most families to use.

Description

technical field [0001] The invention relates to a production method, in particular to a production method of a dual-activation photocatalyst. Background technique [0002] With the improvement of people's living standards, more and more people buy houses in cities. After people buy a house, it is inevitable to decorate the house. As we all know, after the house is decorated, the smell of formaldehyde in the house is heavy. People cannot live in the house directly. They need to open the windows for a period of time to ventilate the house. After the formaldehyde in the house is removed, they can enter the house. , easily harm people's health. At present, after people decorate their homes, they usually choose some deodorizing and air-removing materials to put in the house, so as to quickly remove formaldehyde in the house. Deodorizers, in a narrow sense, refer to chemical preparations used to completely remove gas odors. The odors to be removed are usually foul-smelling, pun...
